Websites for running and sprinting?

Question

I want to start practicing running and sprinting seriously, and I've never done it before. Can someone recommend websites or personal advice for this? I guess I have tight hamstrings, and I'm really not flexible at all, and I don't really know how to stretch, so I'd like to get some advice for that. Also with strength and breathing. Thanks.
